Produced for Radio Telefis Eireann in Dublin, Ireland, 'At Heaven's Door' tells the story of three Irish individuals who stood on the threshold of death and how the experience changed their lives. Debbie McGuiness lost two friends in a St. Valentines Day fire; Larry O'Brien survived the Zeebrugge Car Ferry disaster in Belgium; and Maura McDaid was with her husband Terry in their North Belfast home when gunmen burst in and shot him dead in a case of mistaken identity. These survivors describe their feelings upon getting a second chance at life.
